امروزه به دلیل پیشرفت در بخش نرم افزاری و برنامه های کامپوتری موجود در تمام زمینه های علوم مختلف مهندسی و همچنین به دلیل سادگی و قابل دسترس بودن، اکثر مهندسان برای تحلیل وطراحی از این نرم افزار ها وکامپیوتر استفاده می کنند. یکی از نرم افزارهای مورد استفاده مهندسین عمران برای تحلیل وطراحی فونداسیون ها برنامه safe میباشد . در این نرم افزار رفتارخاک زیرفونداسیون به وسیله فنر های مجزای فشاری که سخت...
OBJECTIVE We have recently described a modification (Veil of Aphrodite) designed to preserve the lateral prostatic fascia (LPF) during robotic prostatectomy. Here, we histologically compare the Veil of Aphrodite technique (VT) and standard nerve-sparing technique (ST). METHODS Thirty-six consecutive prostatectomies performed by a single surgeon were processed by the whole-mount method. The ri...
A number p is a safe prime if both p and (p − 1)/2 are prime. This note describes a method of generating safe primes that is considerably faster than repeatedly generating random primes q until p = 2q + 1 is also prime.
(a) Maximum intensity projection (MIP) of the 200-µm-thick cortical microvascular stack obtained by TPM. Blood plasma was labeled by FITC. (b) Top-view projection of the segmented microvasculature with the intravascular PO 2 measurements obtained by TPM. Mean vascular segment PO 2 measurements were color-coded and overlaid on the segmented microvascular structure. (c) MIP of the OCT image of th...
What is the organization of cerebral microvascular oxygenation and morphology that allows adequate tissue oxygenation at different activity levels? We address this question in the mouse cerebral cortex using microscopic imaging of intravascular O2 partial pressure and blood flow combined with numerical modelling. Here we show that parenchymal arterioles are responsible for 50% of the extracted ...
The defensive peripersonal space represents a "safety margin" advantageous for survival. Its spatial extension and the possible relationship with personality traits have never been investigated. Here, in a population of 15 healthy human participants, we show that the defensive peripersonal space has a sharp boundary, located between 20 and 40 cm from the face, and that within such space there i...
Advances in radiotherapy planning reduced the volumes of irradiated normal tissue and allowed safe dose escalation in prostate cancer. Image-guided radiotherapy solutions to prostate and bladder cancer offer further improvements. The initial process is understanding the causes and extent of internal organ motion, followed by development of equipment and protocols to minimise geographical miss. ...
In immature long bones, radical excision of malignant tumours of the metaphysis may necessitate sacrifice of the adjacent epiphysis. To preserve the adjacent joint while allowing a safe margin of excision, we used physeal distraction before removing the tumour. From July 1984 to August 1992, we operated on 20 patients by this method. After a mean follow-up of 54 months there was no local recurr...
